Lymphatic and Immune System - Exam 3 Study Guide
2024
Lymphatic System - Ans:✔✔-Network of organs and vein-like vessels
Lymphatic System Functions - Ans:✔✔-1. Fluid recovery
(a) Capillaries collect most of fluid they pump out but the 15% that isn't picked up is picked up by
lymphatic system
2. Immunity
(a) inspects & picks up foreign cells & chemicals from tissues
(b) activates immune responses
3. Lipid absorption
(a) small intestine to lacteals to absorb dietary lipids
Components of the Lymphatic System - Ans:✔✔-1. Lymph = interstitial fluid that capillaries didn't pick up
2. Lymphatic vessels = transport lymph (similar to blood vessels)
(a) empty into capillaries which penetrate tissue

(b) collecting vessels to converged capillaries which travel beside veins & arteries and empty into lymph
nodes
3. Lymphatic tissue = cells found in mucous membranes that have roles in defense and immunity
4. Lymphatic organs = defined sites w/ separation from neighboring tissue
(a) red bone marrow, thymus, lymph nodes, tonsils, & spleen
5. Lymphatic trunk
(a) goes to converged collecting vessels
(b) body has 6
6. Collecting ducts
(a) go to converged lymphatic trunks
(b) body has 2
Where does lymph come from and why do we call it lymph? - Ans:✔✔--Comes from interstitial fluid
outside of lymph vessels
-Becomes "lymph fluid" once it enters the lymph vessels
-Plasma in the blood system gets pumped out into interstitial space and becomes interstitial fluid and
gets picked up by lymphatic vessels and becomes lymph fluid
